The ability of the models contributing to fifth Coupled Models Intercomparison Project (CMIP5) represent Southern Ocean hydrological properties and its overturning is investigated in a water mass framework. have consistent warm light bias spread over entire column. greatest occurs ventilated layers, which are volumetrically dominated by mode intermediate layers. layers been observed strong fingerprint climate change impact sequestrating significant amount heat carbon dioxide. layer poorly...
The development of the deep Southern Ocean winter mixed layer in climate models participating fifth Coupled Models Intercomparison Project (CMIP5) is assessed. convection regions are key to ventilation ocean interior, and changes their properties have been related change numerous studies. Their simulation consistently too shallow, light shifted equatorward compared observations. shallow bias mostly associated with an excess annual‐mean freshwater input at sea surface that over‐stratifies...
The representation of the Antarctic Circumpolar Current (ACC) in fifth Coupled Models Intercomparison Project (CMIP5) is generally improved over CMIP3. range modeled transports historical (1976–2006) scenario reduced (90–264 Sv) compared with CMIP3 (33–337 a mean 155 ± 51 Sv. large intermodel associated significant differences ACC density structure. position accurately represented at most longitudes, small (1.27°) standard deviation latitude. westerly wind jet driving biased too strong and...
The advancement of mobile multimedia communications, 5G, and Internet Things (IoT) has led to the widespread use edge devices, including sensors, smartphones, wearables. This generated in a large amount distributed data, leading new prospects for deep learning. However, this data is confined within silos contains sensitive information, making it difficult be processed centralized manner, particularly under stringent privacy regulations. Federated learning (FL) offers solution by enabling...
The Coupled Model Intercomparison Project phase 3 (Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report) models show a consistent intensification and poleward shift of the westerly winds over Southern Ocean during 21st century.However, responses Antarctic Circumpolar Currents (ACC) great diversity in these models, with many even showing reductions transport.To obtain some understanding diverse ACC transport, we investigate both external atmospheric internal oceanic...
We investigate the representation of Southern Hemisphere subpolar gyres in 20 IPCC AR4 climate models. The models reproduce three southern gyres: Weddell Gyre, Ross and Australian‐Antarctic agreement with observations. Some simulate presence a “supergyre”, strong connectivity between gyres. gyre strengths structures show great range across It is found that link wind stress curls weak, indicating Sverdrup balance does not hold for modelled gyres; instead, simulated are mainly determined by...
Abstract. In order to estimate biogeophysical effects of historical land cover change on climate during last three centuries, a set experiments with system model intermediate complexity (MPM-2) is performed. response deforestation, the simulates decrease in annual mean global temperature range 0.07–0.14 °C based different grassland albedos. The effect changes most pronounced middle northern latitudes maximum cooling reaching approximately 0.6 summer. reaches 0.57 spring owing large surface...
